V4L/DVB (10527): tuner: fix TUV1236D analog/digital setup

As reported by David Engel <david@istwok.net>, ATSC115 doesn't work
fine with mythtv. This software opens both analog and dvb interfaces of
saa7134.

What happens is that some tuner commands are going to the wrong place,
as shown at the logs:

Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner 1-0061: tv freq set to 67.25
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: using tuner params #0 (ntsc)
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: freq = 67.25 (1076), range = 0, config = 0xce, cb = 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: Freq= 67.25 MHz, V_IF=45.75 MHz, Offset=0.00 MHz, div=1808
Feb 12 20:37:48 opus kernel: tuner-simple 1-000a: tv 0x07 0x10 0xce 0x01
Feb 12 20:37:48 opus kernel: tuner-simple 1-0061: tv 0x07 0x10 0xce 0x01

This happens due to a hack at TUV1236D analog setup, where it replaces
tuner address, at 0x61 for 0x0a, in order to save a few memory bytes.

The code assumes that nobody else would try to access the tuner during
that setup, but the point is that there's no lock to protect such
access. So, this opens the possibility of race conditions to happen.

Instead of hacking tuner address, this patch uses a temporary var with
the proper tuner value to be used during the setup. This should save
the issue, although we should consider to write some analog/digital
lock at saa7134 driver.

ext4: Implement range_cyclic in ext4_da_writepages instead of write_cache_pages

With delayed allocation we lock the page in write_cache_pages() and
try to build an in memory extent of contiguous blocks.  This is needed
so that we can get large contiguous blocks request.  If range_cyclic
mode is enabled, write_cache_pages() will loop back to the 0 index if
no I/O has been done yet, and try to start writing from the beginning
of the range.  That causes an attempt to take the page lock of lower
index page while holding the page lock of higher index page, which can
cause a dead lock with another writeback thread.

ext4_da_writepages() instead.

Secondly, if CONFIG_PREEMPT=y, this bug solves itself because networking

were running.
